Ch10:Properties of Gasess

Question 1

Gas

Answer 1

is a substance that has no well defined boundaries but diffuses rapidly to fill any container in which it is placed

Question 2

standard pressure

Answer 2

100kPa

Question 3

Boyles Law

Answer 3

states that at constant temperature the volume of a fixed mass of a gas is inversely proportional to its pressure

Question 4

Charles Law

Answer 4

states that at constant pressure the volume of a fixed mass of gas is directly proportional to its temperature measured on the Kelvin scale.

Question 5

Gay-Lussac’s Law of Combining Volumes

Answer 5

states that in a reaction between gases, the volumes of the reacting gases and the volumes of any gaseous products are in the ratio of small whole numbers provided the volumes are measured at the same pressure and temperature

Question 6

Avogadro’s Law

Answer 6

states that equal volumes of gases contain equal numbers of molecules under the same conditions of temperature and pressure.

Question 7

Assumption of the kinetic theory of gases

Answer 7

They have no attractive or repulsive forces

The molecules are negligible compared with space they occupy

Gases are made up of particles that are constantly colliding

Question 8

Limitation to Kinetic Theory

Answer 8

Real gases have attractive or repulsive forces

They are not negligible

Question 9

ideal gas

Answer 9

is one that perfectly obeys the assumptions of the kinetic theory of gases under conditions of temperature and pressure

Question 10

Real gases

Answer 10

have forces of attraction and repulsion do exist between the molecules and the volume of the molecules is not negligible.

Question 11

Volatile liquid

Answer 11

Is one with a low boiling point
